Adapter to connect a PS/2 mouse to a serial port

 ps/2 to serial

If you still have an old computer, the problem is to connect to it modern mouse may be familiar to you. Old mechanical mouse, sooner or later come into disrepair - cable wear, buttons do not work, etc. In general, modern laser mouse is usually much nicer than the devices of the last century

Because the serial mouses are no longer produced, then the for PC without a PS/2 port is still two options: adapt the PS/2 or USB mouse. With PS/2 mouse everything is much easier - this protocol can be implemented in almost any microcontroller, such as ATMega8.

The adapter is built on ATMega8 microcontroller and uses MAX232 to match the TTL signal levels with a serial port levels. The microcontroller receives data from the PS/2 mouse and transmits them via the UART.

Connecting the Joystick from game consoles to your PC

Sega joystick and PC

8- and 16-bit game consoles that were a long time ago very popular, has long lost its leadership in gaming and entertainment market. However, the old games are still popular and yet are perfectly competitive of the interestingness with the modern multi-gigabyte and multi-gigahertz monsters. Today there are many different emulators of old consoles and the Chinese industry is still produced a console itself as well as joysticks to them.

Solderless breadboard - microcontroller designer

This breadboard can be used for temporary prototypes and experimenting with circuit design more easily. It is designed for prototyping circuits on chips in DIP-packages and discrete components. The breadboard is intended primarily for prototyping devices on microcontrollers AVR (ATMega8/48/88/168/16/32/8535/...) and АТ89Сх50. The breadboard is based on 40-pin single row connectors PBS (step 2.54mm) and IC-sockets.
